Confocal Z-scan of (a) FA−DDS (b) FA+DDS with normal medium and (c) FA+DDS having excess of folic acid in the medium (competition inhibition assay) to competitively block the folate receptor on MCF7 cells. These DDS were incubated for 60 minutes in the selected medium. The FA−DDS showed negligible fluorescence after rigorous washing. However, FA+DDS with normal medium (no excess FA in medium) showed homogenous fluorescence distribution while the fluorescence was recorded only on the surface of cells containing excess of FA in the medium.
